As always , for Reception of Tv Stations , trees and tree leaves , plants and plant leaves , have a Negative Effect on Broadcast Tv Reception and so do buildings and and other obstructions including you own building.
Some and not all Negative Effects are.

Multi-Path Reflecting Tv Signals Bouncing All Around.
The Best Practice for Reliable Reception is to Install the Antenna/s at a Location that has the Least Amount to No Amount of Obstructions of Any Type or Kind in Directions of Reception Including Your Own Building.
